A passive safety device starting apparatus includes: a sampling unit for sampling a plurality of acceleration values from an automotive vehicle according to periodic interrupt signals; an integration unit for calculating the sum of a plurality of acceleration values sampled within each of a plurality of first time intervals, for storing a number of the sums, each of which is calculated within a second time interval greater than one of the first time intervals, in a corresponding number of data areas of a memory, and for generating a value of an integral based on the number of the sums within each first time interval; and a starting unit for updating the integral value according to the periodic interrupt signals by adding a new acceleration value to the integral value generated by the integration unit after the new acceleration value is sampled by the sampling unit, and for starting a passive safety device when the updated integral value is detected to be greater than a threshold value. |
